Because iron deficiency anemia is easy to recognize and treat, the non-hematological manifestations of this trace element deficiency have been overlooked. There is a large body of evidence accumulated from animal and human studies to indicate that iron deficiency states are associated with alterations in cellular function, growth, motor development, behaviour and cognitive function. There are consequences for the host's level of immunocompetence against infection, for physical work and metabolic stress, for altered fetal outcome and premature labour in pregnant women. The gastrointestinal functions and other organ systems are also affected as a result of iron deficiency.

The ligand to which the retinoic acid X receptor binds has recently been determined to be either retinoic acid itself or another metabolically derived molecule.

This restriction has been based on the amount of total dietary nucleic acids or all purines, assuming no differences in uricogenic effects of individual purines (adenine, guanine, hypoxanthine, and xanthine). However, inspite of their biochemical similarity, purines are metabolized differently and produce different uricogenic effects in animals and humans. Among the four purine bases, adenine and hypoxanthine have been reported to be more uricogenic than guanine and xanthine. Moreover, free adenine has been shown to be more uricogenic than its nucleoside or nucleotide when fed to animals. Changes in the contents of purines and release of free bases have been reported to occur during various cooking procedures such as stewing, roasting, boiling, and broiling of meat, poultry, and fish products. The differences in metabolic effects of individual purines, and modification in the amount and form of purines caused by processing would suggest that the uricogenic potential of processed foods should be based on the nature and quantity of dietary purines.

Prolactin maintains mammary gland insulin receptors to ensure anabolism. Lactation in IDDM women may be influenced by hyper- or hypoglycemia as women balance their insulin needs. Milk from diabetic animals has decreased lactose, fat, protein and volume and these effects can be reversed with insulin administration. Mature breast milk of IDDM women has increased glucose and sodium and mammary gland lipid metabolism may be impaired. Milk lactose and citrate, markers of lactogenesis II, suggest delayed lactation occurs in diabetic women. Many factors may influence lactation success and breast milk composition of IDDM women.

Human immunodeficiency virus (HIV) and associated opportunistic infections stimulate a broad and complex array of responses which include fever, hypermetabolism, leukocytosis, proteolysis of skeletal muscle, and synthesis, by the liver, of acute-phase reactant proteins and various intracellular enzymes. These responses increase gluconeogenesis and lipogenesis, decrease albumin synthesis, and redistribute and/or sequester various trace elements. Infection-induced depletion of body nutrients serves to weaken host resistance. The deterioration of the nutritional status of these patients is likely to have an important effect on the course of the disease. It is thus evident that comprehensive management of HIV infection must include nutritional evaluation and treatment. When oral nutrition proves to be insufficient to maintain adequate intake, alternative routes must be considered. Selection of an appropriate nutritional support formula requires an evaluation of the absorptive capacity of the gastrointestinal (GI) tract, the length of time required for nutritional repletion, costs, patient acceptance, and feasibility of at-home use. Nutritional support maximizes the ability of the AIDS patient to resist infection, may favor the response to medication by decreasing the incidence of adverse drug reactions, and may prolong the quality and productivity of life.</p>","PeriodicalId":76370,"journal":{"name":"Progress in food & nutrition science","volume":"14 4","pages":"371-402"},"PeriodicalIF":0.0,"publicationDate":"1990-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13246754","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
